Updates tox.ini to use new features

Reasons:
 - tox update v1.6

Changes:
 - tox 1.6 allows us to skip the sdist step, which is slow.
 - It also allows us to override the install line. In this case, it's
   important as it allows us to stop getting pre-release software we
   weren't asking for.

Supports bash_completion for heatclient

bash_completion feature can improve CLI user experience, projects like
nova, keystone, and cinder already support it.

NOTE: this patch just provides simple functionality, which means cache
for IDs and names is not used (like nova).
